ABSTRACT:
A plastic case suitable for housing objects, such as a video cassette, and manufactured by assembling a sandwich of heat-sealable members including a non-heat sealable stiffener member and then moving the assembly to a heat-sealing machine to permanently seal the parts together. To prevent movement of the stiffener member and mis-alignment with the heat-sealable members, one of the heat-sealable members adjacent the stiffener member is provided with a recessed region into which portions of the stiffener member can be pushed and there held in place by an interfering fit until the assembly is permanently sealed together.
